Almost nothing is left of all the things I felt so certain about when I was young.
It’s not just that I didn’t know as much as I thought I knew. It’s worse. What I’ve slowly realized is that much of what I knew at the time — even that which I was certain about — was wrong. I’ve had to unlearn many of those things.
In some ways, it would have been easier if I had simply been ignorant. If I don’t know something, there’s an empty space where truth can eventually fit. I can learn something new and fill in what I didn’t know before.
But when I already “know” something that isn’t true, there’s no empty space. The space is already occupied by something false.
And that false belief changes the way I understand everything else.
I can look directly at evidence that ought to tell me I’m wrong and find some way to explain it away. (I’m really good at that.) I can encounter something that ought to be obvious and fail to see it because it doesn’t fit what I already “know.” I can spend years trying to make new pieces of truth fit into an old framework that was wrong from the beginning.
Sometimes we can’t learn the truth until we first unlearn the falsehood that makes the truth seem impossible.
